H We need to find the torque that makes the disk start rolling Consider the rotation around the center of mass • The force of gravity acts at the center of mass and hence produces no torque • The normal force has zero level arm and hence produces no torque • The force of friction provides the torque 7 • If the object is rolling without slipping the friction force is static

The big assumption was that the friction coefficeint was 1 as im not sure what it should be I am ordering the motors through maxon and had a look at what they had and their motors put out around 5 20mNm for their motors then a gearbox of say 50 1 would be added to the motor then multiply by the motor efficiency 60% give an output of 600mNm
